I like concept and design of this app, but a simple paragraph or menu that details what the colors mean and how to navigate it would be very helpful.

Clean design

Great app. Includes useful information and is overall clean and simplistic in design. The menu and navigation could be easier to use. I found myself jumping around a bit to find where things were. Overall, a handy application.
